BURNER ATTACHMENT.

Specification of Letters Yacent.

Application filed April 6, 1911. Serial No. 619,265.

To all whom, it may concern.

Be it known that I, EDWIN M. LnoYn, a citizen of the United States, residing at San Jose, in the county of Santa Clara and State of California, have invented new and useful Improvements in Burner Attachments, of which the following is a specifi cation. i

This invention relates to an attachment for lamp burners, and particularly pertains to a deviee'for converting an ordinary tnbnlar wick coal-oil lamp into an incandescent mantle lamp.

It is the object of this inventionto provide a simple device which may be readily attached to and removed from the burner of the common oil burning lamp in which a circular wick is employed. such,,for instance. as that known as the Rochester burner, and which device is so constructed and arranged that by its use the Wick burning lamp will be converted into an incandescent mantle lamp.

A further object is to provide an aitm-h- 1 ment for accomplishing the above results,

which may he readily applied to most burners oi the Rochester type without alteration or removal of the humor. and which may he easily put in place or removed by the housewife or other users of the lamp.

By the use of this invention the wick lamp may he quickly converted into an incandescent lamp, or vice versa. thus adapting the lamp to a double purpose.

The invention consists of the parts and the combinationand construction of parts as hereinafter more fully descrihcd and claimed, having reference to the accompany ing drawings, in which Figure 1 is a vertical section of the invention as applied. Fig. 2 is a side elevation of the attachment constituting my prcsent invention. Fig. 3 is an inverted plan view of same.

In the drawings A represents the howl of a coal-oil lamp, Whichhowl may he of any suitable construction. Mounted on the howl A is the ordinary tubular Wick burner. which burner consists of a cylindrical hons ing 2 adapted to he threaded into the month of the lamp howl A and which is surrounded by a perforated casing 3. and a wick advancing tube 4 on the interior of the housing 2, which is reciprocated verticallytherein to raise or lower a wick 5. The tube 4.

may he operated by any suitable mechanism, not necessary to be here shown. The wick 5 surrounds a cylindrical tube 6, which is mounted in the lamp howl A and extends therethrough, this tube opening to the'ibottom ofthe howl A and terminating at its upper open end approximately on a level with the top of the burner housing 2 and Patented Aug, 13, 1912.'

is provided for the purpose of delivering a current of air to the inner up ends of the burning wick 5, this center raft tube 6 being commonly employed in lamps of this character. Formed on the upper portion of the perforated casing 3 is a series of vertically extending spring members 7, disposed at suitahle intervals apart around they casing. which members 7 are adapted to beor against the lamp chimney placed on the casing 3 and retain it in position as is well known in oil burning lamps.

in the ordinary use of this lam the upper end of the Wick 5 saturated with int'lannnahlc oil is advanced a short; distance ZliKH'U the upper ends of the tnhe 6 and housing 2 and ignited. the flame thus generated throwing oil a bright light by reason of the efx'lcnzlorl areas of wick surface and the free supply of air delivered thereto through the center draft tube ('3 and the perforated Casino; fl. The fuel oil supplied. to the flame through the wick 5 by capillary attraction, as is well known.

The essence of my present invention resides in providing a cap 8, shown in detail in Figs. 24%. which is peculiarly constructed and formed. and which is adapted to he placed upon and. attached to the lamp burnt-r inst ied h inserting it Within the annularlv "isposed spring members 'l. as shown in Fig. 1. The cap ll is formed approximately in the shape of a frustum of a. cone. is tubular. and open at both ends. a

The unper end of the cap is bent inwardly a. short oistanee and is adapted to extend into the lower endof a mantle 9 which is supported air-eve the opening in the upper end the cap 8 in suitable nnlnner. The mantle S is of the ordina y type of incandescent mantles. and is here shown as supported on a Wire hrache ll which is mount ed on can 8.

Mounted on the interior of the cap 8 is an annular bathe ringfi'l which is spaced from the in" r walls of the es and concentric therewi n'the ring 11 being connected to the cap 8 by means of tangs 12, as shown in Figs. 1 and 2. Thisbal'tlering 11 is of such inside diameter and is so positioned in the cap 8 that when the latter is placed in po sition on the burner the battle ringwill surround and closely contact with the outer pe-- ripheral surface of the housing 2 ashort dis tance below the upper edge of the latter, as shown in Fig. 1.

As a means of providing a support for a lamp globe suitable to an incandescent burner, and which is not-adapted t0 be-sup ported in the clamp members 7 in the ordinary manner. I have devised a rim 13. which can be placed overgthe clamp members'i, as

"shown in Fig; l, and rests "upon' a flange 14 which is usually formed on the casing at the base of the members 7. This "run 13 has ah0rizon tal. flange orledg'e 15tormed on its'outer facebn which a globelfi' is adapted to rest. 1 1 --The parts being-placed in position on the burner, as shown in Fig.: 1', and the-Wick 5 ignited, a current "of air is caused to enter the perforated casing-3 below the tint-13. which currentpasses upward around the housing 2 until itstrikcs the ring 11, where upon it'is deflected against the inner inclined walls of the cap"8,-'trom whence it is again deflected so as to strike th' flame on the wick in substantially a horizontal direction. At the same time, a currentof' airis delivered to the flame through the center draft tube 6, this} latter current being directed laterally thrbug'h a perforated cap 17 in the upper end of the tube 6, and these currents meeting head on at the'point of combustion conrert thenormal yellow flame of the burning wiekinto a blue flame of intense heat. This hot flame rising'into the interior of moved at any time and the its normal forin.
